Food should be stored on shelves that are at least how far off the floor?

The correct answer indicates that food should be stored on shelves at least 15 cm off the floor. This practice is essential for maintaining food safety and preventing contamination. Storing food off the ground helps to avoid potential contact with dirt, moisture, and pests that can be present on the floor.

Keeping food elevated minimizes the risk of contamination from spills, leaks, or cleaning activities that occur on the floor. Additionally, this height allows for proper air circulation, which is critical for controlling humidity and temperature around stored food items. By adhering to the recommendation of a minimum distance of 15 cm, food service operators and home cooks can ensure that they are maintaining safe storage practices and protecting food from contamination.
